Samsung has developed a completely transparent solar-powered monitor that's designed to be used with ambient light. Though they're marketing it as a television, it's almost certainly going to be used initially as displays in commercial areas, and it apparently is also a touch-screen, opening it up for the coolest kind of kiosk you've ever used. See a video after the jump.

Every LCD panel has a transparent pane inside. You can disassemble the one in front of you and make a similar display. But the glass pane usually is really dark. So the real question is how brightly the scene behind the panel was illuminated.
